FUNGAL FIN ROT
What is it?
Very similar to bacterial fin rot, much the same symptoms appear. Fungal fin rot is caused by fungus spores in the water. They attach to the fins, and begin to grow. It is usually caused by a initial wound on the fins, caused by parasites, nippy tank mates and poor water conditions. Usually only affects stressed fish. Common stresses include overcrowding, poor water quality, malnutrition or sudden temperature changes.

Symptoms:
Frayed, decaying, damaged fins and in very severe cases just a stump is left remaining. Fins may be red at the base, with skin ulcers. The fish would most likely be in poor health so clouded eyes and lethargy are also common.

It is difficult to tell between bacterial and fungal fin rot, but there are some giveaways. Fungal fin rot looks like clumps of cotton whilst bacterial fin rot is not like cotton. Bacterial fin rot is whitish or gray, and although causes the same amount of damage, the growths are not as prominent.

Fungal fin rot usually has a more uniform line of damage, i.e., attacks all areas at the same rate. Bacterial fin rot causes varying damage, from big tears in some areas to little or no damage in other areas.

Cure:
Firstly, make sure the water is of a high quality, check pH and ammonia levels. Correct these and proceed with treatment.

Malachite Green works well here, as do most fungal cures. Adding salt to the aquarium will help with stress.



Remember, water quality is always extremely important- so always check that first as it is often the cause of disease in aquarium fish. When treating sick fish, try to put the least amount of stress on them as possible, as stress will hinder the heeling process. Another thing is to remember is that generally, a healthy fish is a happy fish.
